Okay so the 7 pounds of 1964 nickles I have are not silver so I can add them to the change to cash in at the bank.
LOL, I was saving all 64 and before.
The only year nickels had any silver were 1942 - 1945, and not all 1942 were silver. If you want to see if your 1942 was silver, look at the reverse, it will have a large mintmark above the monticello dome. All 1943 - 1945 were silver and have the same large mintmark above the dome. I generally keep all nickels 1955 and previous, some folks do 1959 and previous.
